Riley. It’s also true that those .280 AI loads generally require a little less powder and thus produce less free recoil energy (all other things being the same). The data used to compare the trajectory and wind drift of the cartridges was obtained from Hornady (here, here, here and here) and Nosler (here). Not surprisingly, the .270 Winchester and .280 Remington have very similar case capacities while the .280 AI can hold a little more powder because of its less tapered case and steeper 40 degree shoulder. Great article and comparison of similar cartridges. This very likely hampered adoption of the cartridge to a certain degree. However, since the .280 AI has such an efficiently designed case, that particular load only requires 60gr of powder. Buy a really good .280 Remington hunting rifle here. Though dimensionally identical to (and thus completely interchangeable with) the original .280 Remington, Remington claimed the new 7mm Express loads had a tiny velocity advantage over the original .280 Remington factory loads when using the same weight bullet. Also, had the 280 Rem been introduced a couple years earlier than the 270 Win, the roles may have been introduced with the 270 struggling to keep up with the 280 Rem, which is more superior to the 270 anyways. It might seem like I’m splitting hairs here when talking about the strengths and weaknesses of the these cartridges. However the ballistic coefficient of equal weight bullets favors .270 caliber bullets over 7mm (.284) bullets of similar design. From Guns and Gear® Season 4, Tom Gresham discusses the .280 Remington. Considering that the 7RemMag came from the same .458, .338, and .264 Magnum (belted) case, when loaded to the same pressure levels and housed in a rifle of 26″, it will exceed any max velocity possible with the .280AI by at least 150fps (hand loaders’ have proven this fact for decades). Since it uses a much larger case diameter, most rifle magazines will hold more .270 Winchester, .280 Remington, or .280 AI cartridges than 7mm Remington Magnum cartridges. program or calculated from the formula given in the Lyman Reloading Handbook, 43rd Edition. You need to carefully analyze your potential needs and choose the one (270 vs 280 Remington vs 280 Ackley Improved vs 7mm Rem Mag) that you think will fit them best. The table below compares the recoil produced by the Nosler loads compared above for those cartridges when fired from a 7.5 pound rifle. shooting Nosler 150 gr. Additionally, the .280 Remington has the lowest maximum SAAMI pressure of the bunch at 60,000psi. All eight loads used a 200 yard zero.Interestingly, the 130 grain .270 load has an almost identical trajectory to the .280 Remington 140 grain Accubond load. Buy some of the best .270 Winchester hunting ammo here. However, the reduced body taper and sharper shoulder can sometimes cause feeding issues with certain rifles. Later, they also offered it in their Model 742 autoloader and Model 760 slide action before finally offering it in the Model 721 and 725 bolt-action rifles.

Before we get started, I have an administrative note: Some of the links below are affiliate links. Others opted to neck down the .30-06 case to use smaller diameter bullets (like the .25-06 Remington), which is what the folks at Winchester did when they modified the case to use .277″ instead of .308″ bullets. The shoulder of the .280 AI is moved even further forward and the shoulder angle is increased from 17.5 degrees to 40 degrees. Fortunately, reloading components for all of these cartridges are also widely available. Anything that you can do with a 130-grain .270 can be done with a 140-grain .280. Interestingly enough, Nosler also publishes a .280 Ackley Improved load with a 140gr bullet at 3,222fps that slightly exceeds the velocity of that particular 7mm Rem Mag load above. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.As you can see, the .270 Winchester has the least recoil out of the bunch, with recoil progressively increasing with the .280 Remington, .280 Ackley Improved, and 7mm Remington Magnum. The Lyman 50th Edition (p197-198, 212-216), Speer Number 10 (p182-184, 193-196, 201-204), and Hornady 10th Edition (p351-355, 391-400, 406-411) reloading manuals were used as references for the history of the cartridges. This prevents .280 Remington ammunition from being chambered and fired in a .270 Winchester chamber. This is why the management at Nosler decided to standardize the .280 Ackley Improve and submit it to the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) for approval, which it received in 2008. Get a good hunting rifle chambered in the cartridge that you think fits your needs the best, learn to shoot it well, use quality bullets, and you’ll be all set for most hunting situations. For those reasons, most 7mm Remington Magnum loads have more energy remaining downrange, a flatter trajectory, and (all other things being equal) will penetrate better than .30-06 Springfield loads using the same weight bullets. The 280 used to be called the 7mm Express, but is now called the 280. Typically, a rifle magazine that can hold 4-5 .270 or .280 cartridges will only be able to hold 3 7mm Remington Magnum cartridges. For this reason, the .30-06 Springfield was an almost instant success in the civilian market. Buy an excellent 7mm Remington Magnum hunting rifle here.

Using 140 gr bullets in the 270win and the 280 rem there's not a nickel's worth of difference. Both of those cartridges are very capable performers, though neither is as well known or as widely used as the .270 Winchester or 7mm Remington Magnum. [Re: yotekyllr] White Eagle Die Hard Member III Registered: 02/26/02 Posts: 2878 Loc: The Dark Side 280 will better either the 270 or the 30-06 a fine round almost perfect if there is such a thing The .280 is one of my ole favorites. Nov 14, 2017 Shooting smaller diameter and (generally) lighter bullets than the other three cartridges, the .270 Winchester has a very flat (though not the flattest) trajectory and the least recoil of the bunch, but also carries the least energy downrange and is the most vulnerable to wind drift. Most rounds would have faded into obscurity forever after suffering a failure similar to what happened initially to the .280 Remington. Mule Deer Cartridge Showdown: .270 Win. Ultimately, the .280 showed an irrelevant 20-50fps gain in velocity over the .270 in barrels of equal length with 140 to 150 grain bullets. The result was a new case with slightly more (usually around 4-5%) powder capacity. The 7RemMag is loaded 3000psi less pressure than the same case of a .264WinMag and 4000psi less than the .280AI (plus the .280AI has a barrel of 2″ longer). Additionally, since it has such an efficient design, the .280 AI doesn’t use as much powder as the 7mm Remington Magnum to achieve nearly the same level of performances. In addition to all being excellent excellent choices for deer sized game, these cartridges are also suitable for bigger creatures under the right circumstances. Furthermore, shot placement and bullet construction / weight is far more important than choice of caliber. I used Nosler’s own reloading data published online (available here, here, here, and here). Your articles are not like that. If one looks at the 270, 280 and the 30-06 one can quickly see that the 280 is the better cartridge. Indeed, the .280 Ackley Improved (280 AI) is one of the newest SAAMI standardized rifle cartridges on the block. The 280 Remington (case length 2.525 OL 3.330) and 270 Winchester (case length 2.540, OL 3.340) are basically the same, with the exception that the .280 shoulder is moved forward about 0.10 inch. So, does that mean the claim that the .280 Ackley Improved can do everything the 7mm Remington Magnum can do, but with less recoil is true? 7-08 vs 280 is about the same as the 308 vs 30-06 discussion. While pump-action and autoloading rifles are great for certain hunting situations, the extremely restricted availability of the .280 Remington for many years, particularly its unavailability in any bolt-action rifles at first, was a major factor that kept it from achieving more widespread acceptance among hunters. Copyright © 2020 Field & Stream. The .270 Winchester has by far the least recoil of the bunch. All rights reserved.

I used the Hornady Ballistic calculator and ShootersCalculator.com to compare trajectory, wind drift, and recoil for the cartridges. 6.5 Creedmoor vs. 270 - which cartridges are an ideal companion when hunting?Finding the answer to this question is no piece of cake. .280 Remington vs .270 Winchester [edit | edit source] The .280 Remington is capable of generating slightly higher velocities with a given bullet weight than the .270 Winchester, and also able to use heavier bullets due to the larger .284" diameter. Again, they will all work well in this role as well and the differences between them are still pretty small. Can the .280 AI really live up to the claim made by some that it can do everything the 7mm Mag can do, but with less recoil? The results are also about what you’d expect for the Hornady Precision hunter loads for those three cartridges. E tips so its ready for CA hunting. However, the fact that it’s still hanging around even after experiencing a bunch of marketing fumbles from corporate management is a testament to the inherent strengths of the .280 Remington. Had it been available in .280Rem I would have got that instead but it wasn’t/isn’t. The .280 Ackley Improved offers a modest ballistic improvement over the .280 Remington in terms of trajectory, wind resistance, and retained energy.
